Step-by-step explanation:

There is not any variability in this question it is just a yes or no question. If the question was "How long does an average person exercise for "

The relationship described in the question between the number of minutes you can talk on a cell phone and the phone's battery charge is correlation. Correlation refers to a statistical relationship between two variables, where as the battery charge decreases, the number of minutes you can talk on the phone also decreases. It does not imply a causal relationship.

The relationship described in the question between the number of minutes you can talk on a cell phone and the phone's battery charge is correlation.

Correlation refers to a statistical relationship between two variables. In this case, as the battery charge decreases, the number of minutes you can talk on the phone also decreases. It does not imply a causal relationship, where one variable directly causes the change in the other.

For example, if the battery is fully charged, you may be able to talk on the phone for several hours. However, as the battery charge decreases, your talk time will gradually decrease until the battery is completely drained and you can no longer use the phone.

The number of minutes you can talk on a cell phone decreases as the battery charge decreases due to a causation relationship.

The correct answer is causation. This is because there is a direct cause-and-effect relationship between the phone's battery charge and the number of minutes you can talk on the phone. As the battery charge decreases, it limits the phone's ability to function, thereby reducing the available talk time.

For example, if your phone starts with 100% battery and allows for 240 minutes of talk time, a drop to 50% battery might only allow for 120 minutes of talk time as the battery depletes. This reduction in talk time is a direct result of the decreasing battery charge, illustrating a causal relationship.

It's important to differentiate this from correlation or association, which would imply a relationship without direct causation. Here, the reduction in battery charge directly causes the reduction in talk time, proving it to be a cause-and-effect relationship.

The vertex of the function y = x2 - 4x + 3 is at (2,-1). You can find this by using the formula -b/2a for the x-coordinate of the vertex and then substituting this x-value into the original equation to find the y-coordinate.

The function you are asking about, y = x2 - 4x + 3, is a quadratic function, and the graph of a quadratic function is a parabola.

The vertex of this parabola can be found using the formula -b/2a for the x-coordinate and then substituting this value into the original equation to find the y-coordinate. For this function, the coefficients a and b (from the general form ax2 + bx + c) are 1 and -4 respectively. Using the formula, the x-coordinate of the vertex is -(-4)/2*1 = 2. We then substitute x = 2 into the original equation to find y = (2)2 - 4*(2) + 3 = -1. Thus, the vertex of the function y = x2 - 4x + 3 is at (2,-1).

density = mass/ volume

volume = mass/ density

volume = 5625 / 15 = 375 cm^3

volume = l x w x h

375 = 5 * 3 * X

375 = 15

x = 375/15 = 25

height = 25 cm

The height of the object is 25 cm and this can be determined by using the formula of density and volume.

Given :

The height of the object can be determined by using the formula of density. The formula of density is given by:

[tex]\rm d = \dfrac{m}{V}[/tex]

where d is the density, m is the mass, and V is the volume.

Now, substitute the known terms in the above formula.

[tex]\rm V = \dfrac{5625}{15}= 375\;cm^3[/tex]

Now, the volume of an object is given by:

[tex]\rm V = l \times w\times b[/tex]

Now, substitute the known terms in the above formula.

375 = 5 [tex]\times[/tex] 3 [tex]\times[/tex] h

Answer:

$ 90

Step-by-step explanation:

Given,

The profit in each card = $ 0.35,

If she sold x cards,

Then the total profit she earned = profit in each card × number of cards

= 0.35x dollars,

According to the question,

0.35x = 42

[tex]\implies x = \frac{42}{0.35}=120[/tex]

Thus, she sold 120 cards,

Now, if the selling price of each card = $ 0.75,

Hence, total earning before paying expenses

= selling price of each card × total cards

= 0.75 × 120 = $ 90

The number 5.78778778 is a rational number because it has a repeating decimal pattern that can be expressed as the fraction 573/99.

The number 5.78778778 is a rational number. Rational numbers are those that can be expressed as a fraction where both the numerator and the denominator are integers.

In this case, the number 5.78778778 has a repeating decimal pattern, which is a hallmark of rational numbers.

We can convert this repeating decimal into a fraction by setting it equal to a variable, say x, subtracting a shifted version of x to isolate the repeating part, and then solving for x to find its fractional equivalent.

If we perform this process, we can turn 5.78778778... into a fraction. For example:

→ Let x = 5.78778778...

→ Multiply both sides of the equation by 100 to shift the decimal two places: 100x = 578.78778778...

→ Subtract the original x from this new equation: (100x - x) = (578.78778778... - 5.78778778...)

→ This simplifies to 99x = 573

→ Divide both sides by 99 to solve for x: x = 573/99

→ This fraction represents the decimal number 5.78778778..., confirming it is rational.

Answer:  

Talia swims about 1.5 miles per hour faster than Alina.

Step-by-step explanation:

Since, 1 miles = 1609 meter and 1 hour = 60 seconds,

⇒ [tex]\text{ 1 miles per hour } = \frac{1609}{3600}\text{ meter per seconds}[/tex]

⇒ [tex]\text{ 1 meter per seconds } = \frac{3600}{1609}\text{ miles per hours}[/tex]

Here, The speed of Alina = 2.5 miles per hour = 2.5 × 1609/3600

[tex]=\frac{4022.5}{3600} \text{ meter per seconds }[/tex]

[tex]=1.11736111\text{ meter per seconds}[/tex]

And, the speed of Talia = 1.8 meter per second,

Since 1.8  > 1.11736111

⇒ Talia swims faster than Alina.

And, the difference between their speeds = 1.8 - 1.11736111 = 0.68263889 meter per seconds

= 0.68263889× 3600/1609 miles per hour

= 1.52734618 miles per hour ≈ 1.5 miles per hour ,

⇒ Fourth option is correct.

Answer:

Length is 20 meters and width is 16 meters.

Step-by-step explanation:

Given: Perimeter of parallelogram is 72 meters.

            Width of the parallelogram is 4 meters less than its length.

To find: Length and width of the parallelogram.

Solution: Let the length of the parallelogram be x meters. So, width of the parallelogram is [tex]x-4[/tex] meters.

As per question,

[tex]x+x+x-4+x-4=72[/tex]

[tex]4x-8=72[/tex]

[tex]4x=72+8[/tex]

[tex]4x=80[/tex]

[tex]x=\frac{80}{4}[/tex]

[tex]x=20[/tex]

Hence, length of the parallelogram is 20 meters, and width of the parallelogram is [tex]20-4=16[/tex] meters.

g + m = 32

g = 3m

3m + m = 32
